Description
基材を提供することであって、少なくとも片面に第1の表面を有する基材、を提供することと;
このような方法、特に追加層の少なくとも第2の表面にはんだ層を適用することによる方法で、追加層が第1の表面に堆積される場合、基材の第1表面が覆われる平面的方法、特に完全に平面的な方法のはんだ層によって覆われ、基材と追加層との間のはんだ層の膜厚は、12um未満、特に7um未満である、追加層及び追加層の第2の表面と第1の表面との間にはんだ層を配置することを提供することと;
基材及び少なくとも部分的にはんだ層を溶融するために第1の表面に配置されている追加層を加熱し、少なくとも1つの追加層に基材を接合すること、によって特徴づけられる。
キャリア材料上にはんだベルト及び追加層の第2の表面上のはんだベルトの適用部をそれぞれ製作するためにはんだ材料の第1の圧延加工をすること;
はんだ層の膜厚が12μm未満、特に未満7μmに達するほどの、そのようなクラッド追加層/そのようなクラッドキャリア材料の第2の圧延加工をすること;及び
必要であれば、焼なまし、若しくは中間焼なまし、又は圧延工程、特に第2の圧延工程の間、又はこの間ずっと加熱すること。
圧延加工処理の間、例えば約5〜10%だけ、クラッドキャリア材料のクラッド追加層のわずかな延伸をそれぞれすること。
これは、更にはんだ層と追加層との間の接合部の改善、及び特に更なる膜厚の低減を可能にする。一実施形態では、本発明はまた、3つ以上の工程、例えば3、4、5、6、7あるいはより多く工程を有する圧延加工処理を提供する。いくつかの工程でのこの方法の実現化は、最終的に、加熱状態の下で非常に少ない膜厚の低減だけが、各工程において達成されなければならないという利点も提示する。
